Slate Plan

Handle $ARGUMENTS.

Use this for repeated "harsh honest, absolute best Slate v2 architecture/DX" review prompts where the failure mode is death by incremental suggestions.

This is a two-phase lane skill.

Planning mode is the default. It creates or updates the execution-grade plan, scores it, and uses the active goal as the durable lane contract until every required pass, issue/reference sync gate, verification gate, and closure score gate is complete. Score is only one input. A high score never permits goal completion by itself; planning completion means the full pass schedule is closed and the plan is ready for user review.
